NFL using DNA to authenticate game balls

TAMPA, Fla. -- Science meets the Super Bowl on Sunday, when the NFL tags each of the 120 game balls with a strand of synthetic DNA to try to deter counterfeiters. The FBI estimates 70-80 percent of sports memorabilia is fake. The DNA stamp is part of a four-tier security system used to authenticate the footballs. "We wanted something covert, something that would force a counterfeiter to go to extremes to get around our authentication efforts," said Dave Gioia, vice president of the parent company of PSADNA Authentication Services.
